Two small suggestions that might make it easier for newcomers to take advantage of the wonderful database:
1. Googling Postgres docs produces links for all different versions. This is because incoming links are to different versions. Besides being confusing, it pushes the pages lower in Google, and makes it harder to find them.
Could the website offer a link to the 'current' version, whichever it is. Eg instead of just :
Have:
which would keep all incoming links pointed to the current page.
2. The 'SQL' in 'PostgresSQL' is hard to say and type. Everyone drops it (even this list!). Why not change the official name? Again, it would make googling and naming things easier.
